Adds a config for a status page using uptime-kuma.
Open questions here included:
- what machine to run this on
(and if a new one how to configure their network bits);
- who could help set the secret in the age file;
- who could set up the application password (currently a manual step in
services.uptime-kuma), after which the stateless client can be re-built;
- what to monitor -- i for now commented some sub-domains i could not
publicly access to test.
We don't need weird Perl scripts where we are going. Here's a streaming
channel-scripts deployment with plenty of bells, including OTLP.
